The Challenge of Channeling Water
From the Romans to the Everglades, the art of directing water flow has never been easy For thousands of years impromptu land surveyors tried, sometimes successfully, to force water to flow in a direction it did not want to go. This was done to help grow crops in areas where water was not abundant enough...
No Barrier Between Land and Water
Innovative tools and technology help hydrographic mapping deliver detailed data in previously inaccessible areas. Underwater mapping presents unique logistical challenges that are increasingly being met with technology used in creative ways, and by combining multiple types of data to develop a complete picture. From unmanned surface vessels (USV) to multi-beam sonar, advanced equipment yields accurate...
What to do With All the Lidar Data
An age-old Aesop’s Fable adage says, “Be careful what you wish for, lest it come true!” When the U.S. Geological Survey (USGS) embarked on the National Enhanced Elevation Assessment (NEAA) in 2012, the goal was to document the national-level requirements for enhanced elevation data. Little did USGS know at the time, the report would be...

Mapping the Surface of the Ocean?
It is crucial that we keep accurate maps of the ocean’s shorelines, but when my company got a request to map the ocean’s surface 50 miles out in the Gulf of Mexico, my initial reaction was: Why? Isn’t the ocean just the ocean that far out? There aren’t any geographic features or elevation changes. It’s...
NOAA Advances Deep Channel Topobathy Lidar for Groundbreaking Alaska Project
Steep and rugged cliffs, rocky shores, changing turbidity, underwater hazards, and unpredictable weather are some of the extreme challenges of mapping the coastline and waters surrounding Alaska. However, a new topobathymetric lidar project for the National Oceanic and Atmospheric Administration (NOAA) conducted by NV5 Geospatial is leveraging a state-of-the-art combination of advanced remote sensing technologies...
